Class TableMap

java.lang.Object
  javax.swing.table.AbstractTableModel
      jwo.utils.gui.TableMap

All Implemented Interfaces:

Serializable, EventListener, TableModelListener, TableModel

Direct Known Subclasses:

TableSorter

public class TableMap
extends AbstractTableModel
implements TableModelListener

In a chain of data manipulators some behaviour is common. TableMap provides most of this behaviour and can be subclassed by filters that only need to override a handful of specific methods. TableMap implements TableModel by routing all requests to its model, and TableModelListener by routing all events to its listeners. Inserting a TableMap which has not been subclassed into a chain of table filters should have no effect.
